LORNE A; GRIFFIN, OF EVANSION, ILLINOIS, ASSIGNOR TO AMERICAN STEAM .CONVEYOR CORPORATION, OFOHIOAGO, ILLINOIS, A CORPORATION OF NEW YORK. r

To all whom it may concern." I

Be it known that I, LORNE A. GRIFFIN, a citizen of the United States, and resident of Evanston, in the county of- Cook and State of Illinois, have invented a certain new and useful Improvement in Ash-Conveyers, of which the following is a full, clear, and concise description, reference being had to the accompanyingdrawings, forming a part of this specification. i

My invention relates to ash conveyors of the conduit type wherein the ash is conveyed through the conduit by the action of a fluid,

such as steam, compressed air or water, and has for its general object the provisionof improved means for facilitating the renewal of any one or more of the conduit sections when said sections become Worn through usage. I

As is now generally known, ash conveyers of this type are made of several metallic sections forming a conduit, which extends from points ator adjacentfurnaces fromwhich ashes are to be removed, to a suitable ash tank or other point where the ashes are to be deposited. v In such systems it has been found necessary to make the several elements or sections of the conduit quite heavy and of comparatively large size, on account of the abrasive action of the ashes that are caused to travel therethrou'gh in the normal operation of the conveyer. Because of the considli erable weight of the sections and because of the meansheretofore employed for supporting the sections of conduit, it has been an ex- 7 tremely difiicult matter to effect replacement and repairswhen such became necessary.

To overcome this objection to the common type of ash conveyer, I providecertain improved means which permit easy and quick replacement of any of the conduit sections.

A further object of the invention resides in providing a combined support and joint hand between two adjacent sections, which, together withthe foregoing, will be pointed out in detail in connection with the accompanying drawings, wherein Figure 1 is a side elevational view of an ash conveyer system embodying the improved arrangements of my invention, some of the parts being shown in section more clearly to reveal theinternal construction,-

Fig. 6 is an enlarged detail cross sectional view taken along the line 6-6 of Fig. 4, looking in the direction indicated by the arrows.

Similar characters of reference refer to similar parts throughout the several views.

Referring first to Fig. 1, the ash conveyer system illustrated comprises a horizontal conduit? provided with a plurality of intake hoppers, one of which is shown at 8, the hoppers being disposed at or adjacent thev furnaces from which ashes are to be re moved. Extending upwardly from one end of the horizontal. conduit 7 is the vertical conduit 9 communicating with a second horizontal conduit 10 extending to an ash tank or some other point where the ashes are to be deposited.

Each one of the conduits 7, 9 and 10 is made up of several elements or sections held in place by clamping bands and arranged to be removed from the system when renewal of the sections becomes necessary or desirable. The horizontal conduit 7 is made up of the several semi-cylindrical sections as shown at 11, 12 and 13. The several semicylindrical sections, as most clearly illustrated in Fig. '3, cooperate to form a continuous cylindrical pipe unit.

To seal the space provided between the lateral. abutting edges of the upper and lower pipe sections, as between the pipe sections 11 and12,I provide the labyrinth joint shown at 14 in Fig. 3, formed by a longitudinal ridge carried by one of the sections, and a cooperating longitudinal groove formed in the adjacent section, the space between the ridge and walls of the groove being filled with a suitable 17 between the filler or grout. The abutting ends of the several sections of the conduit are provided with annular flanges shown at 15 and 16, shaped so as to provide an annular groove conduit sections. This groove is filled with grout made up of a fibrous and cementitious fireproof composition, which may be of the kind described and claimed in patent to James A. Daviess, No. 1,278,869, the filler or grout being held in place by the retaining band shown at 18. Each one of the bands 18 is made up of two semi-cylindrical clamping members, each of which carries the two inwardly extending flanges 19 and 20 which embrace the outer faces of the flanges 15 and 16 formed on the pipe sections; The semi-cylindrical bands 18 are bolted or otherwise secured to the T beams 21, 21, one disposed on each side of the horizontal conduit 7 and running parallel with the 'conduit,as shown in" Figs. 1 and 3. The T beams 21 are supported from the floor by the standards shown at 92, 22. I j v From the construction thus far described it will be observed that all of the sections constituting the horizontal conduit 7 are supported by the T beams 21 through the action of the semi-cylindrical clamps 18. If

the removal of the section shown at 11 becomes necessary or desirable, the 11 per clamps 18 which embrace the ends 0 the section 11 are removed, with theresult that the section 11 is detached from its sup ort.

The section may then be removed an repaired or replaced, and the clamps 18 again bolted to the T beams 21. V

' The elbow forming communication between the horizontal conduit 7' and the vertical conduit 9 is preferably constructed of five parts shown at 23 to 27 inclusive. The section 26 carries two lugs, one of whichis shown at 28, for bolting the sectionto the VT beams. 29 designates a steam nozzle ex- V Figs. 1 and 2. The elbow 31 establishing communication between the vertical conduit 9 and thehorizontal conduit 10 may be made up of several parts, as'is the lower elbow,

or may be made up of one piece, if'such is desired. The upper elbow 31 is carried by a support 32 attached to the elbow by in the conduit does notdi'slodge any of the lugsand boltsshown at 33. If it becomes necessary to remove any one of the sections forming thevertical'conduit 9, as for example,'if it is found necessary or desirable to remove the section-shown at a, the clamps?) and 0 are removed and the section a moved transversely out of the conduit 9. It will be observed that all of the sections above the section a are suspended from the support 32, and all of the sections" beneath the section a, are supported by the T beams 21, 21. After the new section is put in place the annular grooves between the end flanges 15 and Y16 are grouted andtheclamps b and 0 put back in place.

In the modified arrangement of vertical conduit shown in Fig. 4, I m l two T bea'msBl, 34', extending upwardly on oppo site sides of the conduit, and bolted to each one of theclainps 18 -18, as shown in Fig.

5. By this arrangement each one of the conduit sections is supported from the clamp which embraces the upper flange of that particular section. one of the sectionsis' independently supported from the T beams 34, 3 1.

i From the above description it will be ob-' served that each one of the clamps 18 performs th'e double function of supportingone or more sections of the conduit, and of retaining the grout in place in the annular groove 17, so that the pressure created withthe fi'ller'. p

Having-thus described invention, what I claim asnew anddesire'to' secure by Letters Patent'of the United States is:-

1.- 1kI1 tlSl1 conveyer' comprising a conduit consisting of a plurality ojf'sections disposed end to end, a supporting framework for the conduit, and means attached to the framework for sealing the joints between the opposing edges of adjacent sections and for supporting the sections from the framework.
